The True Value of a Sample Composition Is There  [PDF]
Hong Yi, Wei Yi
American Journal of Analytical Chemistry (AJAC) , 2015, DOI: 10.4236/ajac.2015.64027
Abstract: The core objective of a chemical composition measurement is to determine its true value. However, when measuring the composition of a macroscopic sample with a large number of atoms or molecules, realizing the true value of the measurand at both the macroscopic and microscopic levels remains an unsolved theoretical problem. We find that the true value of a sample composition exists in any subsample of a homogeneous molecular population of the sample. Here, we propose the Central Law of Measurement of the Amount of Substance: “The homogeneity of a sample molecular population represents the measurement accuracy of the sample composition in an analytical procedure”. The Central Law is based on a homogeneous molecular population axiom in which the molecular composition of a sample is identical for any homogeneous subsample. Furthermore, we point out that, at the microscopic scale, Avogadro’s law does not hold true.

Skyhook Surface Sliding Mode Control on Semi-Active Vehicle Suspension System for Ride Comfort Enhancement  [PDF]
Yi Chen
Engineering (ENG) , 2009, DOI: 10.4236/eng.2009.11004
Abstract: A skyhook surface sliding mode control method was proposed and applied to the control on the semi-active vehicle suspension system for its ride comfort enhancement. A two degree of freedom dynamic model of a vehicle semi-active suspension system was given, which focused on the passenger’s ride comfort perform-ance. A simulation with the given initial conditions has been devised in MATLAB/SIMULINK. The simula-tion results were showing that there was an enhanced level of ride comfort for the vehicle semi-active sus-pension system with the skyhook surface sliding mode controller.
A Dam Break Analysis Using HEC-RAS  [PDF]
Yi Xiong
Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.36047
Abstract: This paper firstly described the dam break in the aspects of theories and models. Break parameters prediction, the understanding of dam break mechanics, peak outflow prediction were shown as the essential for the dam break analysis, and eventually determined the loss of the damages. Secondly, as an application example, Foster Joseph Sayers Dam break was further modeled and analyzed using USACE Hydrologic Engineering Center’s River Analysis System (HEC-RAS) model based on available geometry data. The results show that dam break is a complicated and comprehensive process involving lots of principles. Combination of mechanics and case studies, reflection of predominant mechanisms of headcut erosion, more specific categorization of dam, prudent investigation and inference of dam break process are needed in developing a satisfactory dam break simulation model. Foster Joseph Sayers Dam break due to piping elongates the time period of high water surface level, which increases the duration of risk. However, the dam break does not increase the downstream maximum water surface elevation (Max. W.S. Elev) significantly at previous design Probable Maximum Flood (PMF). Dam break has a greater impact on the downstream location where is closer to the dam in accordance with the comparison of the hydrographs at different downstream locations. Sensitivity analysis demonstrates that the changes of dam break parameters had no much influence on the downstream Max. W.S. Elev.

Abstract: Let F be a meromorphic functions family on the unit disc Δ, If for every (the zeros of f is a multiplicity of at least k) and if then and ( ), then F is normal on Δ.
Ben-Naim’s “Pitfall”: Don Quixote’s Windmill  [PDF]
Yi Fang
Open Journal of Biophysics (OJBIPHY) , 2013, DOI: 10.4236/ojbiphy.2013.31002

Ben-Naim in three articles dismissed and answered the Levinthals paradox. He announces there are pitfalls caused by the misinterpretation of thermodynamic hypothesis. He claims no existence of Gibbs free energy formula where the variable is a protein’s conformation X . His Gibbs energy functional is G(T, P, N, P(R)), where the variable is probability distributions P (R) of the conformations. His “minimum distribution Peq is wrong. By carefully establishing thermodynamic systems, we demonstrate how to apply quantum statistics to derive Gibbs free energy formula G(X). The formula of the folding force \"\" is given.

Fixed Point of a Countable Family of Uniformly Totally Quasi- Ø -Asymptotically Nonexpansive Multi-Valued Mappings in Reflexive Banach Spaces with Applications  [PDF]
Yi Li
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.49A002

The purpose of this article is to discuss a modified Halpern-type iteration algorithm for a countable family of uniformly totally quasi- ? -asymptotically nonexpansive multi-valued mappings and establish some strong convergence theorems under certain conditions. We utilize the theorems to study a modified Halpern-type iterative algorithm for a system of equilibrium problems. The results improve and extend the corresponding results of Chang et al. (Applied Mathematics and Computation, 218, 6489-6497).

Motivation and Attitude: Two Important Non-Intelligence Factors to Arouse Students’ Potentialities in Learning English  [PDF]
Yi Liu
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.514140

This paper discusses how to arouse students’ potentialities in learning English by using two important non-intelligence factors: motivation and attitude. With the need to address the diversity of language learners in the contemporary ESL context, the value of non-intelligence factors cannot be underestimated. There are several non-intelligence factors that influence success or failure in English learning, but the two major ones include motivation and attitude. Motivation drives students towards a desired goal, while attitude shapes students’ perceptions of the curriculum, peers, as well as the instructor. It is important for language educators to recognize the value of these factors if quality outcomes in terms of English learning are to be delivered.

Whether China’s State-Owned Commercial Banks Constitute “Public Bodies” within the Meaning of Article 1.1 (a) (1) of the Agreement on Subsidies and Countervailing Measures: Analysis of US—Definitive Anti-Dumping and Countervailing Duties on Certain Products from China  [PDF]

US—Definitive Anti-Dumping and Countervailing Duties on Certain Products from China is the initial WTO dispute in which China claims that US-countervailing duties on certain products from China are inconsistent with the obligations of the United States under the Agreement on Subsidies and Countervailing Measures (“SCM Agreement”). In this dispute, the specific meaning of “public bodies” within Article 1.1 (a) (1) of the SCM Agreement and the question of whether China’s state-owned commercial banks (“SOCB”) constitute “public bodies” are the heart of the matter. This thesis will analyze these issues by examining the reports of the Panel and the Appellate Body. In particular, the thesis will argue that the theory of the governmental function advanced by China is much more persuasive than that of governmental control in terms of defining “public bodies”. Although China’s SOCBs have gone through several stages of reforms, the majority ownership of them has remained in the hands of the Chinese government. However, SOCBs’ policy-oriented nature has been largely marginalized, and currently they only perform subsidiary governmental functions. In this regard, the conclusion this thesis will attempt to reach is that the WTO system needs to give developing countries like China more policy flexibility in order to upgrade their international trade participation to the level required and followed by developed countries. During the process, developing countries should also make the best use of their latent comparative advantage and the effects of globalization.

The Impact of Brand Image on Consumer Behavior: A Literature Review  [PDF]
Yi Zhang
Open Journal of Business and Management (OJBM) , 2015, DOI: 10.4236/ojbm.2015.31006
Abstract: The concept “brand image” has drawn significant attention from academics and practitioners since it was put forward, because it played an important role in marketing activities. Although brand image was recognized as the driving force of brand asset and brand performance, few studies have elaborated on the relationship between brand image and brand equity. Based on the brand image theories, this study reviewed extant studies about the impact of brand image on consumer from perspective of customer equity. It also presented the shortcomings of current research and pointed out the trends for future study.
